FOR THE FORECAST, THE TROUGH OVER THE NORTHERN GULF OF CALIFORNIA WILL
SUPPORT FRESH TO STRONG SW WINDS OVER THE NORTHERN GULF THROUGH
TONIGHT. NORTHERLY SWELL NEAR GUADALUPE ISLAND OFF BAJA
CALIFORNIA NORTE WILL SUBSIDE THROUGH THIS EVENING, BUT BUILD
BACK INTO THE REGION TUE NIGHT INTO WED FOLLOWING A WEAK COLD
FRONT MOVING INTO BAJA CALIFORNIA AND THE GULF OF CALIFORNIA. TO
THE SOUTH, BROAD LOW PRESSURE IS DEVELOPING OFF GUATEMALA. LITTLE
DEVELOPMENT IS EXPECTED OVER THE NEXT FEW DAYS WHILE THE LOW
DRIFTS TO OFF SOUTHERN MEXICO, BUT STRONG NORTHERLY GAP WINDS
WILL DEVELOP IN THE GULF OF TEHUANTEPEC STARTING TUE. THESE
HIGHER WINDS MAY EVENTUALLY AIDE IN ENVIRONMENTAL CONDITIONS THAT
ARE MORE CONDUCIVE FOR TROPICAL DEVELOPMENT OF THE LOW LATER IN
THE WEEK. THERE IS A MEDIUM CHANCE THAT A TROPICAL DEPRESSION
FORMS WHILE THE SYSTEM MOVES TO OFFSHORE SOUTHERN MEXICO TOWARD
THE END OF THE WEEK OR THIS WEEKEND.
